Abstract
A method and a device for implementing a method for ascertaining the load condition with an exhaust-gas component of a component arranged in an exhaust-gas region of an internal combustion engine is provided in which an increase in the exhaust-mass flow of the internal combustion engine and a detection of a pressure change in the exhaust-gas region in front of the component is specified. The load condition of the component is determined from the pressure change.
Claims10
A method for ascertaining a load condition with an exhaust-gas component of a component situated in an exhaust-gas region of an internal combustion engine, the method comprising:
- providing an increase in an exhaust-mass flow of the internal combustion engine to induce a pressure change in the exhaust-gas region in front of the component;
- providing a detection of the pressure change in the exhaust-gas region in front of the component;
- and
- determining the load condition of the component from the pressure change.
A device for implementing a method for ascertaining a load condition with an exhaust-gas component of a component situated in an exhaust-gas region of an internal combustion engine, the device comprising:
- means for providing an increase in an exhaust-mass flow of the internal combustion engine induce a pressure change in the exhaust-gas region in front of the component;
- means for providing the detection of a pressure change in the exhaust-gas region in front of the component;
- and
- means for determining the load condition of the component from the pressure change.
